What Size of a Backpack for Preschool? The Ultimate Guide

When it comes to sending your little one off to preschool, there are numerous decisions to make. From choosing the right school to preparing them emotionally, every step counts. One crucial aspect that often goes overlooked, but plays a significant role in your child’s daily routine, is selecting the appropriate size of a backpack for preschool. In this comprehensive guide, we’ll delve into the factors you should consider when choosing the ideal backpack size for your preschooler, ensuring both comfort and functionality.

Why Does Backpack Size Matter?

Before we dive into the nitty-gritty details of selecting the perfect backpack for your preschooler, let’s understand why size matters. A backpack that is too large or too small can have adverse effects on your child’s well-being:

1. Comfort

A backpack that is too big may overwhelm your child, leading to discomfort and even physical strain. On the other hand, a backpack that is too small might not be able to accommodate all the essential items your child needs for the day.

2. Health

Improperly sized backpacks can lead to health issues such as back pain, poor posture, and muscle strain. Preschoolers are still developing physically, making it crucial to ensure their backpack fits them properly.

3. Organization

A well-fitted backpack enables your child to stay organized, keeping their school supplies, snacks, and personal items in an order. This not only makes their day more efficient but also fosters good habits early on.

Factors to Consider

Now that we understand the importance of choosing the right backpack size, let’s explore the key factors to consider:

1. Age and Height

Preschoolers come in all shapes and sizes, so there’s no one-size-fits-all answer to the question, “What size of a backpack for preschool?” Take your child’s age and height into account. A backpack that suits a taller, older preschooler might not be suitable for a younger, smaller one.

2. Capacity

Consider what your child needs to carry in their backpack. Preschoolers typically require essentials like a change of clothes, snacks, a water bottle, and perhaps a favorite toy or blanket. Choose a backpack with enough capacity to accommodate these items comfortably.

3. Adjustable Straps

Look for a backpack with adjustable shoulder straps. This feature ensures that the backpack can be customized to fit your child’s unique body shape, providing maximum comfort and support.

4. Weight Distribution

Opt for a backpack with multiple compartments or pockets. This allows for even weight distribution, preventing any unnecessary strain on your child’s back. Additionally, compartments help with organization, making it easier for your preschooler to access their belongings.

5. Durability

Preschoolers can be quite rough on their belongings. Invest in a backpack made from durable materials that can withstand the wear and tear of daily use.

Finding the Right Fit

Now that you’re equipped with the knowledge of what to look for, let’s explore how to find the perfect fit:

1. Try Before You Buy

Visit a store that specializes in school supplies and backpacks, if possible. Have your child try on different backpacks to see which one feels the most comfortable and suits their frame.

2. Check the Straps

Ensure that the backpack’s straps can be adjusted to fit snugly but not too tightly. The straps should sit comfortably on your child’s shoulders without digging in.

3. Consider Growth

Keep in mind that your child will continue to grow. While it’s essential to have a well-fitting backpack now, consider whether it allows for some growth to avoid having to replace it too soon.


How do I measure my child for the right backpack size?

To measure your child for a backpack, use a soft measuring tape. Measure from the base of the neck to the lower back, and across the shoulders. These measurements will help you find the perfect fit.

Can I buy a bigger backpack for my child to grow into?

It’s best to choose a backpack that fits your child comfortably now. An oversized backpack may cause discomfort and potential posture issues.

Are there any safety precautions I should consider?

Ensure that the backpack doesn’t exceed 10-15% of your child’s body weight to prevent strain. Also, teach your child how to properly wear the backpack, with both straps on their shoulders.

What should I pack in my child’s preschool backpack?

Pack essential items like a change of clothes, snacks, a water bottle, and any required school supplies. Keep it lightweight and manageable for your child.

Can I wash a preschool backpack?

Check the manufacturer’s instructions. Many preschool backpacks are machine washable, but some may require handwashing. Always remove any items from the backpack before cleaning.


Selecting the right size of a backpack for preschool is a crucial decision that can impact your child’s comfort, health, and organization. By considering factors like age, capacity, adjustable straps, weight distribution, and durability, you can make an informed choice that will benefit your preschooler throughout the school year.

Ensuring your child’s well-being and setting them up for success starts with the basics, and choosing the right backpack is a fundamental step in that journey. So, when preparing your little one for preschool, remember that a well-fitted backpack is more than just an accessory—it’s a tool for their growth and development.
